Tripodal P₃^XFe-N₂ Complexes (X = B, Al, Ga): Effect of the Apical Atom on Bonding, Electronic Structure, and Catalytic N₂-to-NH₃ Conversion.

ABSTRACT: Terminal dinitrogen complexes of iron ligated by tripodal, tetradentate P₃^X ligands (X = B, C, Si) have previously been shown to mediate catalytic N₂-to-NH₃ conversion (N₂RR) with external proton and electron sources. From this set of compounds, the tris(phosphino)borane (P₃^B) system is most active under all conditions canvassed thus far. To further probe the effects of the apical Lewis acidic atom on structure, bonding, and N₂RR activity, Fe-N₂ complexes supported by analogous group 13 tris(phosphino)alane (P₃^Al) and tris(phosphino)gallane (P₃^Ga) ligands are synthesized. The series of P₃^XFe-N₂^[0/1-] compo
